Referring now to [the] Figures l and 2, 30 represents a base on which the various mechanisms are assembled, Extending upwardly from the base is a vertical bracket support 31 on which is mounted an electric motor 32 having a cable cord 33 with a plug 34 for connection with a wall receptacle. This motor is secured to the bracket support 31 by bolts 35. Upon the upper end of the bracket support 31 is a shelf bracket 36 secured to the support by bolts 37 and [supporting] mounting a reduction gear mechanism 38 that is secured to the bracket member 36 by bolts 39 Fig. 2]. The electric motor 32 has a pulley 41 that is connected by a pulley belt 42 with a pulley 43 of the reduction gear mechanism 38. The pulley 43 is connected to an input shaft 44 of the gear mechanism 38 and this shaft has a worm 45 that connects with a worm wheel 46. The worm wheel is connected to an output shaft 47 that has [an] operating cams 48, [a cam] 49, (Fig. 12) [a cam] 50, [a cam] 51 and [a cam] 52. These cams are longitudinally spaced from one another on the shaft 47.

Extending upwardly from the base 30 are two transversely spaced parallel guide plates 53 and 54 providing a slot or space 55 through which paper tape 56 is passed and worked to form the [inner] package [part] insert. This tape is provided by a tape roll 57 mounted on an upwardly inclined plate support 58 fixed at its lower end to the base 30. Also on the support 58 is an idler and tensioning roll 59 over which the tape extends and is directed to the space 55 between the plates 53 and 54. The idler wheel 59 is pivoted on a pin 61 fixed to an arm 62, Fig. 7, and pivoted at 63 at the opposite side of the support 58. The pin 61 extends through an arcuate and elongated slot 64 so that the arm 62 can lie on the oppo site side of the support 58 from the idler pulley 59. A tension spring 65 connects with a pin 66 on the swing arm 62 and is anchored to the inclined vertical support upon pin 67. The spring 65 will keep a tight rearward pull on the portion of the tape which is passed into the space 55. The roll 57 is supported upon pin 68 and will automatically stay in place thereon due to the inclined position of the support 58. y

The tape S6 is [forced] fed through the space 55 by spaced pairs of driving rollers. The first pair of rollers includes upper and lower rollers 71 and 72, Fig. 7, and the second pair of rollers include upper and lower rollers 73 and 74. On the plate 53 there is journalled a large intermittently rotated gear 75, Figs. 1 and 12, that is operated from cam 49. This cam 49 is in the form of a true eccentric and supports in its ring portion 76 and operating arm 77, the end of which is pivotally connected by a pin 78 to a crank 79 that is pivoted on bolt 81 and which, as in Fig. 13, has a spring pressed pin 82 that engages with any of arcuate slots 83 that respectively have closed ends 84,v in succession, to step the gear 175 on its pivot connection on the plate 53. A shaft 85 is journalled in the plates 54 and 55, [Fig 13,] and the gear 75 is secured to [the] this shaft. The crank 79 is rotatable upon the .shaft and will accordinglv be [worked] rocked by the arm 77. The detent [end] pin 82 is urged toward a wear plate 86 having the slots 83 and fixed to the gear 75 by a compression spring 87 'housed within a retaining cup 88 and bearing against the enlarged end of the pin 82.

This gear 75 will intermittently drive pinion gear 89 disposed therebelow and also through this pinion gear there lwill be driven another pinion gear 90 located [thcrebelowl below pinion 89. The upper driving rollers-71 and 73 are respectively secured to shafts 91 and 92. These shafts in turn respectively have gears 93 and 94 connected thereto. These gears 93 and 94 mesh with the pinion gear 89 to be driven thereby in the same direction.

The lower rollers 72 and 74 are respectively fixed to shafts 95 and 96 that have respectively driving gears 97 and 98 which mesh with the gear 90 to be driven by the same so as to have the upper and lower rollers to act in unison to pull and [force] feed the paper tape 56 through the space 55. The driving gears 89 and 90 are respectively fixed to shafts 99 and 100 that extend through the spaced plates 54 and 55 for journal connection therewith. In this manner, the tape will be advanced intermittently through the space 55.

On the roller 71, Figs. 7 and 24, are converging cutting projections 102 adapted to notch the sides of the tape at two locations, as indicated at 103, and other cutting projections 104 angled therefrom but converging in a different direction provide notches 105 in the side of the tape. Between the sets of notches there is a length 106 that serves to provide the bottom of the inner package part [and] or insert of the assembly and] Portions indicated respectively at 1,07 and 108 outwardly thereof [serving] serve to provide the guide side ends of the upper package part Figs. 7 and 24]. The finished upper part is indicated at 108. The formed portions of this upper part 109 are shaped by devices to be presently described and to form portions 106', 107 and 108'. The portions 107 and 108 are formed at the same time while still connected and are severed by a knife 110. The portions 107 and 108 are formed with the parts shown more clearly in Figs. 8 and 9. Upon the base 30 is a plate 111 having upstanding guide posts 112 on which a die plate 113 is supported by compression springs 114. This die plate contains a die member 115 adapted to engage with the top faceof portion 4 107 of the paper tape. This portion is supported by a bottom die 116 having a dovetail formation 116' thereon about which the portion 107 of the paper tape is to be folded to obtain the final shaped portion 107 and 108'. The die plate 113 carries operating members 117 and 118 which have respectively opposing inclined faces engageable with pivotable fingers 119 and 120, respectively, to cause theirinward movement over the edges of the tape portion 107 and to force these edges into the cut away sides of the dovetail projection 116. These finger projections are pivotally supported respectively on pins 121 and 122 in such a manner that they can pivot inwardly at their upper ends and are restrained against this inward pivotal movement by a tension spring 123 connected between extension pieces 124 and 125 of these fingers. These fingers are normally urged to their outward positions, as shown in Fig. 8, by the tension spring` 123 and are moved inwardly to assume positions shown in Fig. 9 to finally form the portions 107 and 108.

In order to form the bottom portion 106 from the blank bottom 106 there is provided under the same die plate 113 an arrangement such as shown more clearly in Figs. l0 and 1l. The upper contacting member 115 or die is slightly differently shaped, as indicated at 126, to have upwardly converging inclined sides over which the edges of the portion 106 of the tape are folded. Extending respectivelv at opposite sides of the dies are pivotable fingers 127 and 128 pivoted respectively upon pins 129 and 130 and normally are held downwardly inclined by telescoping spring assemblies 131 and 132 respectively, supported respectively in holes 133 and 134 of the plate 111. As the die plate 113 is moved downwardly, pivot fingers 127 and 128 are engaged at their upper ends and their inner ends are pivoted upwardly to pick up the edges of the portion 106 and wrap them about the inclined edges of the portion 126 of the die or guide member whereby to form the bottom portion .106 of the upper package part.

On the upper part of the die plate 113 are bearing blocks 136 and 137 supported respectively upon shims 138 and 139 and in which is journalled a shaft 140 carryinga roller 141. This roller is engaged by the cam 51 so that the die plate 113, which forms a parti of a unit assembly including the members for working the paper portions 106, 107 and 108 and the base 111 and which project through large openings 142 in the respective laterally spaced vertically extending plates 53 and 54 [.1 is recivrocazed.

With the inner package part 109 already formed, except for the severing of the same from the succeeding parts on the tape and for the bending up of the guide portions 107 and 108', an outer package part 143 must be unfolded and positioned to receive the inner part 109 and cookies 144.. On the base 30 there is mounted a mechanism 145 serving to retain and release one at a time folded outer package parts 143. This mechanism comprises (Figs. 1 and 15) an angle section member 146 secured by bolts 147 to the base plate 30. These parts 143 are held at one end by a small catch 148 biased to an elevated position by a spring 149 and pivoted, as indicated at 150, upon a guide member 151 secured to up standing ange portion 152 of support member 146 by bolt 153. The opposite end of the folded parts 143 are held by a guide member 154 which has a small lip projection 155 on its end, Figs. 15 to 22. The stack of folded outer parts 143 is advanced and urged toward the catch 148 and the projection 155 by a weighted arm 156 engaging with the end of the stack and slidable along a guide bar 157. A chain 158 connects with the arm 156 and passes over a pulley 159 iournalled on a bracket A160 and downwardly through a hole 161 in the base plate 30. On-the end of the chain there is fixed a weight 162.

Normally the folded outer parts 143 are held, as shown in Fig. A15. To release the end of the outer packaging parts 143, a triangular-shaped dividing member 1,63 is urged in the direction of the arrows so that its pointed end will enter between parts 143 and by Wedging action separate the parts 143 from the stack and forcibly depress the catch 148 against the action of spring 149,- in the manner as shown in Figs. 16 and 17, to lift the end. of the frame part over the catch 148. A wire spring finger 164 carried on a-post 165 on the base- 30 will hold and retainthe end of the part 143 upon the side of the wedge 163 until control -of 4the part is assumed by othermembers. y 1

sagess- New that the folded frame part 143 has been releasecL, it next has to be shaped and delivered.' to a station `beneath the upper packaging part 109 and the cookies '144; For this purpose a long member 166 is adjustable lIomgvitudinally along the base 30 and has a` projection 167 adapted to engage with the end of the folded packaging part 143 and upon its continued movement,y as shown in Figs. 19, 20 and 21, will open the part. The projection 155 will continue to hold the part 'while this forming is beingcarried on and will restrain it even after the projection4 167 has moved it beyond its unfolded open position, in the manner as shown in Fig. 2l, so as to give tothe part suicient set so that it will not return to its folded position. Thereaften the part 143 will release from the projection 155,. as shown in Fig. 22, and be delivered'to its station beneath the upper part and the cookies.v During this movement,` a long. pivoted nger 168 will engage with the part 143 to stabilize it while being moved by the member 166 and to finally deliver it to*` its position under the upper part and cookies. This finger 168 is. pvo-tally connected to the forming member 166, as indicated at 169; and is thereby pulled by -the member 166. Its pivotal movement is controlled by a cam slot 170. in a cam plate 171 fixed by bolts 172 to the base 30. This ca m groove 170 has a bend and a depending pin projection 173 travels in the groove 170, Figs. l, l5 and 23.

The triangular-shaped member or wedge 1.63 is op.- erated' from cam 48 driven by the drive shaft 47. This wedge 163 is carried on an arm 175,v Fig. 2,4 and this arm projects upwardly from beneath the base plate 30 through an elongated slot 176. Arm 175 is xed to a shaft 177 extending transversely of. the base 30 and journalled in depending brackets 178 and 179. On the opposite end of; the shaft 177 is an arm 180 that is connected by a longitudinally extending link 181 to the lower end of a lever 182 which is pivoted on a support 183 at' 184 and which has a cam follower 185 on its upper end that en gages with the cam 48. The cam 48 is shaped' to give the properl timed movement to the wedge 163.

The. forming and moving member 166 is also operated by cam 48 and in sequence to the operation of the wedge 163. The same cam surface of the cam 48 which is used for the wedge 163 is used for the member 166, Figs. 2 and 3, and accordingly the wedge and the forming and moving member 16.6 are operated in sequence.

The member 166 moves along the top surface of the basef plate 30. A rigid arm extends from the member 1.66 through an elongated slot 187 in the base 30 and is slidable therealong. This upright member is indicated at. 188. Connected tothe underside of the base plate. 30 are brackets 189 and 190 which support guide rods. 191 and^1'92 on which travels a slide 193 integrally connected to the' upright member 188 which carries the member 166. At' one end of the slide 193 there is. connected a link 194 that is pivotally connected to a transverse pivot arm 1.95 at 196. This pivot arm is iixed to a vertically extending shaft 197, Fig. 2. A tension spring 198V is anchored to the under side of the base plate 30 by a bolt 199land is connected to a pin 200 on the arm 195. The vertically extending shaft 197 is journalled in an upstanding sleeve projection 201 on the upper side of the base plate 30 and has a collar 202 lixed thereto by a screw 203. This collar 20.2 holds the shaft 197 on the upper end of the sleeve projection 201 against downward displacement.. The shaft 197 will be rotated in the sleeve 20.1 by a projection 204 from the collar 202 and having cam follower 205 bearing against the cam.

A tension spring 207 is connected to a pin 208 on the lower end of vertically extending lever 182 and is anchored to a pin 209 connected to the bottom face of the baseplate 30.

The outer package part 1.43 is, as shown in Fig. 5, finally located under a support 209. This support has a slot. 2'10 for receiving the finallyv severed upper package part 109 and. spaced cookies 144 disposed on opposite sides of a plunger 211 which forces. the cookies downwardly with the inner packaging part 109 to fold upwardly the end guide portions 107' and 108 and to force the bottom. 106 into the outer packaging part 143. The plunger 211 is shouldered on the opposite sides thereof, as indicated at 212, a distance to receive one cookie or equal to the thickness of the cookie. Due to the shape of the end portions 107' and 108' the cookies Wilb beA held in. spaced relationship' at the opposite sides thereof and provide' thereby an opening in the package for receiving the ice cream or. other filling upon the iinished product being delivered from the present machine.

The plunger 211 is operated by the cam 50 on. the shaft 47. Extending upwardly from the plunger 211 are longitudinally spaced guide sleeves 213 and 214 which are slidable through. a longitudinally extending member 215.V Above the sleeves 213 and 214 there is a frame member 216 having depending rods 217' and 218 respectively for slidably retaining the sleeves 213 and 2114A A block 219 is connected between the` upper ends of the sleeves 213 and 214. In this.. block is an elongated .slot 220 towhich a pinV 221 on the end of a long bent arm222 extends.. This. arm 222 is pivoted upon a projection. or shaft 223 secured to the outer face of the vertically extending supporting plate 53.. A boss 224 is provided on the upper' edge of the plate 53 to which an. anchor pin 225, Fig. 4, is connected. A tension spring 226 is connected to the pin 225 and to a fastening'screw 227 on the arm 222; This spring. 226 serves tol-ift the arm1222 and consequently raises the plunger 211. The same spring 226 will maintain the arm 222 against the cam. 50 and the cam 50 will operate the arm 222 against the action of the spring 226. A spring 228 is connected to a boss 229 on the arm adjacent the pivot shaft 223 toassist spring 226. The upper end of this spring 228 is connected. to a pin 230 projecting from a bracket 231 on the upper edge of the supporting plate 53.

The cookies 144 are [retained] supported, as in Figs. 5 and 6 in inclined cookie chutes 234 and 235 provided at theirv lower ends respectively with a long central slot 236 and two small slots 237 and 238 disposed respectively at the opposite sides of the central slot 236. In order to retain the cookies while they chutes are located in place in the machine, a gate 239 is provided on` the end of the chute. This gate has a handle projection 24.0 and a pivot pin 241 connects this gate with av support ing projection 242 on the side of the chute. Once the chutes are in place the gate 239 is lifted.

These chutes are inclined and in order to straighten the cookies to vertical positions so that they may be received by the. plunger 211, [Fig 5,] brush elements 243 and 244 are used. Guide sleeves 245 and 246 respectively retain the brush elementsv and the bristles of the brushv elements are cut on a bias to enter the large slot 236 of each chute. The brush bristles will act upon the lower edges of. the cookies [and cause] to straighten [them] and separate them from one another so that they will. be evenly fed to the vplunger and prevented from jamming. l

The brush sleeves 243 and 246. are respectively su ported on inclined plates 247 and 248 and [respectively having] have' grooves for receiving the sleeves. At the opposite side of each sleeve and in each plate are spaced small brushes 249 and 25'0 which are respectively carried inA handle elements 251 that are made secure to the plates within holes thereof by set screws 252. These brushes 249 and 250 support the cookies 144 above the slot and in alignment therewith until struck by the shoulders 212 of the plunger 211.

To operate the brushes 243 and 244, (see Fg..4) a lever 253 is pivotally connected to some part of the frame at254 and has a rigidly connected arm extending inwardly from its upper end, as indicated at 255, for engagement by a pin 256 extending from plunger 211 Fig.v 4]. There is a similar arrangement at each side of the plunger so that the brushes 243 and 244 will be moved inwardly and against the lower edges of the cookies simultaneously with the upward movement of the plunger. The weight of the arms 255 may be sufficient to cause slight retraction of the brush elements for the next inward stroke.

The knife is pivotally connected to a xed member of the machine and is operated by a link 258 connected at its lower end, as indicated at 259 to the knife 110 to pivot the same about its pivot connection 260. The upper end of the link 258 is connected to a lever 261 pivoted upon the machine frame and engageable by an abutment 262 fixed to an upstanding projection 263 of the arm 222. Every time the arm 222 is moved down the knife 110 is pivoted upwardly to sever thel paper tape side portions. The knife 110 accordingly is operated when the plunger is operated and by the same main cam 50 which [operates] shifts the arm 222. A tension spring 264 is connected to the link 258 to normally position and retain the knife 110 elevated to permit the movement of the formed paper tape therethrough. This springA is eases 4gchored to a fixed part of the machine, as lindicated at While the cutting operation is effected, the paper tape is locked against any play, as in Fig. 14, by a device 266 that is operated by cam 52. This lever device 266 is pivoted by a pin 267 upon the vertical support plate 545. The end of the lever has a hook formation 268 adapted to engage with an arm 269 on shaft 91 of the paper driving roll 71. A spring 270 acts upon the lever 266 to urge the same toward the cam 52. The lever 266 has a wear plate 271 for engagement with the cam 52.

In order to effect the adjustment of the nal package consisting of inner and outer packaging parts and the cookies, cam 48, as in Fig. 2, through its projection 272 on its side face operates a lever 273 pivoted at 274 on a fixed part 275 of the machine frame whereby to push inwardly a rod 276 slidable in blocks 277 and 278 resting on the machine base 30`and having a plunger member 279 adapted to abut the side face of the assembled package so as to move the same out of its position under the opening 210 of the frame 209 and to [make] provide room for the making of another assembly. A spring 280 surrounding the rod 276 returns the rod 276 with the plunger plate 279 when the rod 273 is not under the influence of the proiection 272 on the face of the cam 48.

The cookie chutes 234 and 235 are respectively supported in their inclined positions by brace rods 284 and 285 held respectively in place by thumb nuts 286 and 287. The lower ends of the brace members 284 and 28S are held respectively by bolt and nut means 288 and 289.

It should now be apparent that there has been provided a package forming machine for forming and assembling outer and inner packaging parts and cookies and wherein the inner packaging part is formed and cut from paper tape passed between spaced vertical plates. will be further seen that the outer frames are formed and moved into position beneath a plunger which serves to assemble the inner frame or part therewithin along with the cookies and wherein the cookies are provided by removable trays arranged in inclined fashion and adapted to cause the cookies to be advanced respectively to the opposite sides of the plunger and through the engagement with a shoulder thereof they are taken along with the inner packaging part into the outer packaging part.

It will also be seen that the cookies are easily adi vanced by the use of brushes operating under the lower ends of the inclined cookie chutes to properly cause the cookies to be brought to their vertical positions for engagement with the plunger. It will be further apparent that a single drive shaft having five cams thereon Itv is operable to effect the motions to the various operating parts for performing the several functions.
